Newer ones are working as an input and output condition-controlled step-up converter, supplying a single 400V filter capacitor from a wide-range input source, usually between 80 and 240V. Video cards can sense whether you have plugged a 6 pin or 8 pin cable into an 8 pin connector so the video card can impose some kind of restriction when The resistance of connectors tends to increase as they are plugged and unplugged so after enough uses they can overheat and even melt when passing a large current. As described in the above sections, the 24-pin main power connector was introduced with the ATX12V v2.0 specification, and there are more and more motherboards providing 24-pin power connector sockets (many
